NHTSA Complaint #11682792 — 2021 FORD F-150

My 2021 Ford F-150 5.0L V8 with the 10-speed automatic transmission has ongoing and severe transmission issues that create a dangerous safety hazard. The vehicle intermittently loses power and feels like it slips completely out of gear while driving, including at highway speeds. This sudden loss of acceleration is unsafe and could easily lead to an accident. The most severe issues occur between 2nd and 4th gear. The truck slams in and out of gear, hesitates, and lurches violently. Shifting often feels like the transmission is “hunting” for the right gear, and hesitation occurs throughout other gear ranges as well. At times, it feels like a new driver learning to operate a manual transmission—jerky, unpredictable, and unsafe. This is not an isolated problem. After researching on multiple owner forums, I found many other 2021 F-150 owners reporting the exact same issues: slipping out of gear, hard shifts between 2nd–4th, hesitation, loss of power, and violent shifting. These widespread complaints strongly suggest a defect in the design or function of this 10-speed transmission. This is not just a drivability issue—it is a critical safety concern. I have lost power while merging and while traveling at highway speeds, leaving me unable to accelerate when needed. In city driving, the hesitation and gear slamming create dangerous situations when crossing intersections or pulling into traffic. Given the number of owners reporting similar problems, I believe this is a systemic defect that requires immediate investigation and action. Ford needs to address this transmission failure before it leads to crashes, injuries, or fatalities.
